A urinary catheter is a small, flexible tube that can be inserted through
the urethra and into the bladder, allowing urine to drain. The urethra is the
tube that carries urine from the bladder out of the body.
indwelling Foley catheter remains in place continuously. To keep the catheter
from slipping out, there is a balloon on one end that is inflated with sterile
water after that end is inside the bladder.
